Inbound fee udpates are rather broken in lightning as they can impact the non-fundee despite the funder paying the fee, but only in the dust exposure it places on the fundee. At least lnd is fairly aggressively high in their (non-anchor) fee estimation, running the risk of force-closure. Further, because we relied on a fee estimator we don't have full control over, we were assuming our users' fees are particularly conservative, and thus were at a lot of risk to force-closures. This converts our fee limiting to use an absurd upper bound, focusing on whether we are over-exposed to in-flight dust when we receive an update_fee. |
